The Federal Court action adds to what is already proving to be costly legal fallout for the German company as it faces class action lawsuits in Australia and around the world over emissions fraud, as well as penalties from antitrust authorities.
Already in Australia, law firm Maurice Blackburn is seeking more than A$100 million ($75 million) from the company, including the full replacement cost of some 90,0000 vehicles, while the auto giant has agreed to pay its 650 U.S. dealers $1.2 billion (913.31 million pounds) in compensation.
In Australia, the ACCC said it wanted the company to make public declarations of misconduct, pay unspecified financial penalties and issue corrective advertising in relation to its actions over five years.

A Volkswagen representative was not immediately available for comment.
